1 Cigarette a Day Still Raises Heart Disease Risk: Study

The findings come as the U.S. is considering how to regulate "heat not burn" cigarettes.

Smoking just one single cigarette a day can significantly raise your risk of heart disease and stroke, researchers said in a new report that contradicts the notion that cutting way down from heavy smoking drastically reduces risks, NBC News reported.

A team led by Allan Hackshaw at the UCL Cancer Institute at University College London went back through credible health studies dating back to 1946.

For men, smoking one cigarette a day on average raised the risk of heart disease by 48 percent over a non-smoker, while smoking 20 cigarettes a day doubled the risk.

For a woman, smoking one cigarette a day raised the heart disease risk by 57 percent and 20 cigarettes a day raised the risk 2.8 times.

"No safe level of smoking exists for cardiovascular disease,” Hackshaw’s team concluded.
